Yolk-shell nanoparticle, method and applications

A nanoparticle and a method for fabricating the nanoparticle utilize a decomposable material yoke located within permeable organic polymer material shell and separated from the permeable organic polymer material shell by a void space. When the decomposable material yoke comprises a sulfur material and the permeable organic polymer material shell comprises a material permeable to both a sulfur material vapor and a lithium ion within a battery electrolyte the nanoparticle may be used within an electrode for a Li/S battery absent the negative effects of battery electrode materials expansion.

Titanium disulfide-sulfur composites

A titanium disulfide-sulfur (TiS$_{2}$—S) composite particle contains a titanium disulfide (TiS$_{2}$) substrate having solid elemental sulfur (S) disposed directly on a surface of the TiS$_{2}$. The TiS$_{2}$ substrate has a layered crystalline hexagonal structure of space group P-3 ml and includes at least 100 distinct layers. The TiS$_{2}$ and S are present in the composite in a weight ratio (TiS$_{2}$:S) of 20:80 to 50:50. Cathodes and batteries containing the composite particle, as well as related methods, are also disclosed.

Porous Fe3O4/S composites for Li/S batteries

Provided are porous Fe3O4/sulfur composites. The composites are composed of porous Fe 3 O 4 nanoparticles and sulfur, where the sulfur loading is 70-85% by weight based on the total weight of the composite. Also provided are batteries having cathodes containing porous FE 3 O 4 composites of the present disclosure.
